INTRODUCTION
GENERAL INFORMATION
Carefully read the use and maintenance manual before start-up the motor. The
use and maintenance manual must be placed near to motor installation location
in order to guarantee operators easy access to the instruction manual. For further
information please contact Italgroup.
R8D series motors are radial piston hydraulic motors (generally indicated as LSHT motors,
low speed high torque motors) with a rotating shaft (1) and a stationary housing (2). The pi-
stons (4) are located radially and the working fluid provide the mechanical force that push
the pistons against the eccentric shaft, providing the shaft ouput torque. The inlet and outlet
flow to and from the pistons is regulated by a distributor (5), that provides the oil distribution
correct timing. The pistons transfer the forces to the eccentric shaft through a connecting rod
(3). Acting in the adequate way (increasing or reducing the oil flow coming from the pump)
the motor rotational speed can be increased or reduced. The motor design guarantee extre-
mely high starting torque and high mechanical working efficiency. Respecting the limitation
of working parameters (indicated into the technical datasheets) and all recommendations (in-
cluding fluid recommendations), high motor lifetimes are obtained and very low maintenance
requirements are needed.

ATF (automatic transmission fluid) oils, SAE 10-20-30 W oils, multigra-
de motor oils (SAE 15 W 40, 10 W 40), universal oils, can also be used.
Always fill the motor (please refer to the “DRAIN RECOMMENDATIONS”
section) with the selected hydraulic fluid before motor start-up. Du-
ring cold start-up avoid high-speed operation until the system reach
the working temperature, in order to provide an adequate lubrication.
Every 5-8 °C of increase respect to the optimal working tempera-
ture for the selected oil, the hydraulic fluid life decrease of about
40-50% (refer to “OXIDATION” section). Consequently, the mo-
tor lifetime will be affected by the working temperature increa-
se respect to the optimal working temperature of the selected oil.
The maximum continuous working temperature is 70 °C, the tempera-
ture must be measured from motor drain line. If the motor doesn’t have
a drain line, the temperature must be evaluated at the return line port.
Oxidation Hydraulic oil oxidizes with time of use and temperature. Oxidation causes
changes in colour and smell, acidity increase or sludge formation in the tank.
Oxidation rate increases rapidly at surface temperatures above 60°C, in these
situations oil should be checked more often.
The oxidation process increases the acidity of the fluid; the acidity is stated in
terms of the “neutralization number”. Oxidation is usually slow at the begin-
ning and then it increases rapidly.
A sharp increase (by a factor of 2 to 3) in neutralization number between
inspections shows that oil has oxidized too much and should be replaced
immediately.
Water content Oil contamination by water can be detected by sampling from the bottom of
the tank. Most hydraulic oils repel the water, which then collects at the bottom
of the tank. This water must be drained off at regular intervals. Certain types
of transmission oils and engine oils emulsify the water; this can be detected
by coatings on filter cartridges or a change in the colour of the oil. In such
cases, obtain your oil supplier advice.
Degree of contamina- Heavy contamination of the oil causes wear rising in hydraulic system compo-
tion nents. Contamination causes must be immediately investigated and reme-
died.
Analysis It is recommended oil being analyzed every 6 months. The analysis should
cover viscosity, oxidation, water content, additives and contamination. Most
oil suppliers are equipped to analyze oil state and to recommend appropriate
action. Oil must be immediately replaced if the analysis shows that it is exhau-
sted.

When the motor is moved from one place to another always be very ca-
reful and act in a way that the motor is stable and under control during
movimentation (refer to handling and storage section for more details).
Before mount the motor, check carefully the absence of damage happened
for example during transportation and/or storing.
For mounting dimensions please refer to the R8D installation drawings. The
motor must be installed using the correct screws size (we recommends the
use of 10.9 and 12.9 class resistance fixing screws) and must be placed on
a structure that is capable to correctly support the motor during functioning:
for this reason the structure must not only be able to support the motor
weight but must also assure the absence of vibration during operation and
must win the reaction forces that are generated by the working torque. Re-
garding the motor fitting design, the concentricity between the centering
diameter (spigot) and shaft (both splined or parallel) must be assured with a
strict tolerance (please refer to the following general indication). If the con-
centricity between the shaft and the centering diameter and/or fixing holes
is not respected, in the worst case the motor can have an unusual failure or
can work only with low performances. Splined adaptors (splined billets) are
available upon request.

The motor can be mounted in any position (refer also to drain recommenda-
tions section). In run-away conditions you must use counterbalance valves.
When the motor is installed vertically with shaft pointing upwards, consult our
technical department. If the motor is connected to high inertial loads, the hy-
draulic system must be designed to prevent peaks of pressure and cavitation.
Consider the use of relief valves, possibly directly mounted on motor distributor
in case the application can generates pressure peaks at the motor ports: the
relief valve should be able to discharge all the flow (or at least a good part of
it) with a limited pressure increase. Italgroup can provide differents valve types
that can be placed directly on the motor distributor (please refer to Italgroup
valves technical catalogue).
Motor case and pistons must be completely filled with oil before starting.
Do not load motor to maximum working pressure instantly. During cold start-up
avoid high-speed operation until the system reach the working temperature.
Connect the case drain directly to tank, and avoid excessive drain line pressure
losses (the case drain pressure must not exceed 10 bar continuous pressure for
R8D serie standard motors). The case drain port on the motor must be located
on the highest point of the installation to ensure that the motor will always be
full of oil. (See drain recommendations page for more details)
Maximum oil temperature must not exceed 70°C. Heath exchangers must be
used with higher temperatures. The operating fluid viscosity must always be
higher than a certain minimum value (see “fluid recommendation” section) in
order to guarantee an optimal motor internal lubrication. When the working
conditions cause the motor case overheating above a critical value, the motor
flushing is required. Flushing consists in the introduction of fresh oil (taken from
the hydraulic circuit) into the motor case. Oil must be taken from the return line
to avoid internal motor damage (the continuous motor case pressure must be
maximum 6 bar). Flushing is an important operation that can be very effective
to improve motor lifetime with heavy duty working conditions and improve the
motor mechanical efficiency.
The motor flushing, if the motor works in one direction only, can be easily
performed connecting the motor return line to the lowest motor drain port. The
highest motor drain port must be connected to the tank. For D75 and D90 flow
distributors, the side 1/4” metallic plugs can be used for flushing circuit instal-
lation: infact the plug (corresponding to the return line port) can be removed
and the connection between motor low pressure port and motor case can be
correctly realized.

Minimum speed is very low and can reach values near to 0.5-1 rpm (depen-
ding on motor displacement). In case of low speed vibration a reasonable
back pressure can eliminate or minimize the vibration and noise level (a
general guideline value can be defined by 5-8 bar back pressure). For
more information please contact our technical department.
Back pressure limit for R8D series motors is 70-80 bar (back pressure oc-
curs for example when hydraulic motors are installed in series circuit). High
back pressure values are often responsible of motor overheating, so if drain
temperature reach values that bring the oil viscosity under the recommen-
ded limit (refer to fluid recommendations section), perform appropriate mo-
tor flushing and/or reduce the back pressure.
During start-up and in the period immediately after it, any hydraulic instal-
lation must be regurarly and carefully checked at frequent intervals. The
working pressure must be checked in order to understand that it agrees
with the design values. The drain line pressure for standard motors must
not overcome 10 bar continuous. If leakage occurs, check the reason,
correct it and carry out new measurements. Check all lines, connections,
screws, etc, and tighten if necessary. Replace contaminated fluid immedia-
tely.
During handling operations, make sure that the motor shaft and tachometer
shaft (if present) don’t receive any hit, in order to avoid motor damage.

R8D series motors are supplied together with plastic plugs, that keep the
hydraulic oil (that was used during final test in Italgroup testing workbench)
inside the motor. A thin oil film is present on the internal motor parts, where-
as the external parts are covered with antirust oil that prevents damage from
oxidation and corrosion.
Therefore the motors can be safely stored into the customer warehouse
without performance losses for long periods (up to 4-6 months).
The storing location must has some important characteristics:
- room temperature comprised between -15°C and +55°C without fast and/or
excessives temperature excursions;
- low relative humidity;
- absence of aggressive and corrosive medias in the motor nearings.
In particular, if motor should be motionless for more than 4-6 months, it must
be protected against internal rust. Proceed as follows:
- fill the motor case with hydraulic oil. After that the motor case is full of oil,
close it with a screw plug;
- fill the motor also from inlet or outlet port. Turn the shaft by hand (the shaft
must make about one revolution) and finally close the inlet and outlet ports.
Please note that the plastic plugs are necessary not only to keep the hydrau-
lic oil inside the motor, but even to avoid that dirt and other fluids (like water
for example) can enter into the motor and create damage during storing or
during motor start-up. Therefore make sure all drain ports, supply ports and
discharge ports are closed during motor handling and storing. If plugs are
missing, use plastic plugs or adequate systems in order to guarantee that
the motor is well protected by dirt and other fluids.
R8D series motors are internally lubricated by the operating fluid, if the motors
are used according to the technical data reported into the R8D catalogue, they
need very limited maintenance operations. In order to achieve good perfor-
mances, long bearings lifetime and safe working, the working fluid must be
carefully selected in function of the operating parameters (a fundamental para-
meter is the ambient temperature range). In case of fire resistence fluid usage
, some limitation on pressure and speed can be required. Refer to hydraulic
fluid recommendations section for more information. If required please contact
Italgroup technical department for further information.

Please note that the theoretical lifetime can be different from the real
lifetime, especially in case of heavy duty applications with continuous
work cycle.
Motor creep speed The hydraulic motor is able to hold the load acting as a brake (if proper
valves or circuit are considered and installed), but a certain creep spe-
ed is always present: this is typical of all brands hydraulic motors.
The motor creep speed depends by many factors, like operating condi-
tions (motor displacement and type, pressure load on the shaft, oil visco-
sity, type and temperature)
Speedy-sleeve
A special inox sleeve is available upon request. In case the motor is used
in aggressive medias or environments, this can be very useful in order
to protect the motor shaft surface located in proximity of the motor shaft
seal. This improves the shaft and seal endurance respect to wear and
corrosion. The ordering code is SPSL. Please contact Italgroup S.r.l. for
more information.
Standard R8D motors are supplied with high pressure shaft seals, the
continuous drain pressure must be maximum 6 bar, whereas the peak
drain pressure must be maximum 10 bar. In case the drain line can or
must has a higher pressure, special shaft seals are available upon re-
quest. The ordering code is HPS. The drain pressure with HPS shaft seal
can reach 20-25 bar continuous pressure and 30 bar peak pressure. The
HPS shaft seal is bi-directional also, so it can be used for example in un-
derwater applications. Please contact Italgroup S.r.l. for more information.
Counterclockwise rotation
Standard R8D motors are supplied with clockwise distributor timing. Ple-
ase refer to the installation drawings of each section for more informa-
tion. With ordering code CCW the motor is supplied with counterclockwi-
se rotation timing. Contact Italgroup for more information.
